Hue Cell
Oct 2, 2026 — A daily color solitaire. It plays like FreeCell, but the cards are paint chips, and it's scored like golf.
Hue Cell is a FreeCell-style solitaire played with paint chips instead of cards. There are four color families, two warm and two cool, and each runs through nine shades from pale to deep. You stack a chip on one a shade deeper from the other side, warm on cool or cool on warm, the way cards alternate red and black. You fill four strips from lightest to deepest, so a won game ends as four finished gradients.
It's a daily game, like Mob.day and Case the Joint, and everyone gets the same deal. Nearly every FreeCell deal can be won, so winning isn't the score. The score is how few moves you needed. A solver finds each day's shortest solution, and it's fast enough to run in the browser: about a tenth of a second for the daily board. Par is that perfect line plus two, so birdies and eagles exist, and matching the solver earns a 💎 Perfect. Moves to the strips are free and so is undo, but your first finish is your score. The free cells shrink through the week, four on Monday down to one on Sunday.
When you finish, the solver replays your game and finds the moves where you lost strokes. They show as a row of squares: blue for a move that kept pace with the perfect line, orange for one that didn't. That row is also the share line, so it says how you played without giving away the deal. Then you can watch the perfect line play out on the board.
There's a harder Color only mode that hides the numbers and symbols, so you judge every shade by eye. There are eleven palettes, and a choice of how warm and cool chips are marked. "Warm" and "cool" turned out to be hard to keep in your head mid-game, so by default warm chips sit on cream card and cool chips on charcoal, which makes the alternation as easy to see as red and black. It's plain HTML, CSS and JavaScript with no libraries. The colors are defined in OKLCH, so every shade is equally dark in every palette, and they're fitted to what a screen can show. The promo is rendered from the real game: one day's deal played along its 12-move perfect line, with every chip playing its shade's note.
